Subject: [PATCH] net: ethernet: mtk_wed: introduce mtk_wed_buf structure
Introduce mtk_wed_buf structure to store both virtual and physical
addresses allocated in mtk_wed_tx_buffer_alloc() routine. This is a
preliminary patch to add WED support for MT7988 SoC since it relies on a
different dma descriptor layout not storing page dma addresses.

Subject: [PATCH] net: ethernet: mtk_wed: do not configure rx offload if not
supported
Check if rx offload is supported running mtk_wed_get_rx_capa routine
before configuring it. This is a preliminary patch to introduce Wireless
Ethernet Dispatcher (WED) support for MT7988 SoC.

Subject: [PATCH] net: ethernet: mtk_wed: introduce mtk_wed_buf structure
Introduce mtk_wed_buf structure to store both virtual and physical
addresses allocated in mtk_wed_tx_buffer_alloc() routine. This is a
preliminary patch to add WED support for MT7988 SoC since it relies on a
different dma descriptor layout not storing page dma addresses.

Subject: [PATCH] net: ethernet: mtk_wed: introduce partial AMSDU offload
support for MT7988
Introduce partial AMSDU offload support for MT7988 SoC in order to merge
in hw packets belonging to the same AMSDU before passing them to the
WLAN nic.
